The True Strength of Weight Gainers
Serious weight gain requires serious calories. However, those who need the extra calories most often have the toughest time consuming enough of them. For many aspiring to be bigger, a highly-active metabolism, weaker appetite and on-the-run lifestyle can make it a real challenge to consume enough calories through whole foods alone.

Add two heaping scoops of Serious Mass to a blender filled with 24 oz. of water. Blend for 45-60 seconds. Then add a few ice cubes and, if desired, other calorie-contributing ingredients and blend for an additional 30-45 seconds.

Tips: Mixing two scoops of Serious Mass with 24 fl. oz. of nonfat or low fat milk instead of water will give you a thicker, creamier, higher-calorie shake. New users may find it beneficial to begin with 1/2 of a serving daily for the first week and then gradually increase to 1 or more full servings several times a day.

Serious Mass is a weight-gain supplement that can be used to feed serious calorie needs in a variety of different ways.*

Between Meals: Drink 1/2 - 1 serving of Serious Mass between meals to maintain positive nitrogen balance and support a high-calorie diet.*

Love this stuff! Tastes great, mixes better with milk than water. For this Ecto-Endo guy (read: string bean), finally a supplement that is having positive results.*

This stuff is GREAT! and taste very good. I will say that 1 serving is too much as its too much calories and carbs for ur body to even absorb. Instead take 1/2 a serving per sitting and this will work very very good*
